Alpert, the mysterious character who never ages, will be playing a large role in Season 6.
Nestor Carbonell told TV Guide that he will be appearing in 16 out of the 18 episodes of the final season.
LOST is notorious for not telling the actors what is going to happen in advance, and Nestor says he is “most curious to know” how old Alpert is.
So are we.
